Model-based hazard analysis method on automotive programmable electronic system

With the increasing number and functional complex of automotive electronic equipment, more risks from systematic failures and random hardware faults may occur. In light of the fact that a failure of an automotive programmable electronic system may lead to injuries and even loss of life it is extremely important to perform the hazard analysis during the process of design and development of these systems to minimize the risk of the occurrence of such disastrous events. In this paper, a comprehensive hazard analysis method based on functional model is proposed. This method overcomes the narrower scope of individual techniques while obtaining the benefits of all of them. The process of functional modelling and safety analysis is outlined and the proposed hazard analysis method is applied to Automated Mechanical Transmission (AMT) control system and the analysis results are integrated.
